As an update to those who helped me with the posts, I'm at an ilevel of 510 now and I still can't kill him, even pushing 120k dps. I don't think I've ever been so frustrated in my entire time playing WoW as I am right now.

I think i did it at 512. The most important advice i can think of for this boss is take your time. I died plenty to retarded stuff, like eating the chaos bolt/"forgetting" that the hounds spawn etc, when just tunneling the boss. So take it easy'ish.

So here's few things i noticed/found online.

When the boss starts to summon fel hounds, move your pit lord to the left side of the gateway, cast rain to the gateway and move to the left. Havoc+CB the first 2 hounds and use the charge+flames on the third along with your nuke.

Before the doomlord spawns(or during the summon), re-enslave the pitlord(i had a macro to dismiss it), then charge+flames on it and soulshatter and you don't have to worry about the doomlord anymore during the fight.

Remember to re-cast your tele as you have to use it due to the 1min cd on the gateway.

And most of all, don't give up on it. At worst, get few more pieces of gear and kick his a$$. :P

*edit* i also specced to unbound will and pretty much kept it on cd along with imp dispel from the GrimSac.

Tried a few times pre 5.4 and was never able to get it. I know people say skill > gear for this but i wont lie, having better gear definitely helped me i think. I didn't even get to the 2nd set of felhunters this time before he died.

I finally got this done this week. Whew. I wiped an awful lot in learning what to do. For me the problem was always the Fel Hunters. It seemed that no matter what I did they removed the enslave from the Doomlord. In the end it just came down to timing. Once I realised that I really didn't need the Doomlord any more once the Catacylsm after the imps had been interupted I was ok. I just send the DL off straight after the interupt to the left beside the portal. In 5.4 you're tanking the boss anyway so as long as you are dispelling the dots off yourself using your talents instead of the Doomlord once you send him off it's ok. Then get him back on the boss as soon as you kill the Fel Hunters of course.

My other big learning was to use the Doomlord's Fel Fire thing on yourself every single time it's on cooldown. Those DoTs'll kill ya really fast.

Quick update, I stopped doing the fight after I posted here (lock at 510 ilevel), and I just went back in today (528 ilevel) and decided to give it a go while I was waiting for my friends. I failed on my first attempt (I forgot ALOT of stuff I needed to do,like redoing talents and such) and beat him on my second try without even pushing him to summon imps a second time. I found hound a LOT easier this time around since I could pump up to 1mill Chaos bolts out.

THANK YOU GUYS FOR ALL THE HELP!!! I really needed that boost of encouragement to not give up, .

I did it about a week ago with ilvl 535 gear. Not gonna lie, it made a HUGE difference. I straight up ATE a doom bolt and walked it off (no defensive cooldowns whatsoever). Was still a fun fight, and I love the green fire. Slight complaint: my fire with glyph of nightmares is still orange -_-

decided to finally do this quest even though I've had the codex since 5.2. I'm a casual and I have 534 ilevel, but I wanted to get the cloak before I started. I picked up purification potions flasks, and int pots.

honestly you just have to do the fight. thanks SO much for all the guides, they really helped. Twilight ward couldn't soak a chaos bolt, but unending resolve, sacrificial pact, then LOSing the 1st and 4th one. I just did this today and it took me about 11 pulls to do it. once I could get to the dogs, everything was great.

This boss should be like a challenge mode with a flat ilvl reduction upon entering.
I got the codex the first day you could get it and the boss was challenging in my gear.
A friend couldn't kill it in ilvl 530 so I logged on his account to kill it for him and OMG it was just a zerg, way to easy.
